Choosing the Right Utility Interconnected Photovoltaic Inverters

Photovoltaic system have become an important means for many countries to cope with power shortages, cut electricity bills and reduce carbon emissions. As the core device connecting solar panels, battery systems, city power and power loads, the performance and system adaptability of the inverter directly determine the power generation efficiency, system stability and return on investment. Utility interconnected photovoltaic inverters are the key solutions in current mainstream home, commercial and industrial photovoltaic energy storage projects.

What are utility interconnected photovoltaic inverters?

Utility interconnected photovoltaic inverters, also known as solar inverters, refer to Photovoltaic systems that have the ability to interconnect with the public power grid. The inverter can not only convert the direct current (DC) generated by photovoltaic panels into alternating current (AC) for home or commercial loads, but also has the ability to feed excess electricity back to the power grid. Unlike traditional off grid inverters, Utility Interconnected Inverter usually also supports working in conjunction with battery systems to achieve flexible switching between energy storage and grid connection, meeting users' dual needs for "power safety + maximum benefits".

How do Utility interconnected photovoltaic inverters work?

Utility interconnected photovoltaic inverters have highly intelligent energy management capabilities. The system uses photovoltaic power generation to power the load first during the day, and the excess power will be used to charge the battery or directly fed into the grid; at night or in rainy weather, when there is insufficient solar energy, the inverter will automatically switch to the mains or battery power supply mode to ensure uninterrupted power supply; once the grid fails, it can also seamlessly switch to off grid mode within milliseconds to continue to power the load. This ability of flexible switching and energy integration is irreplaceable in distributed energy systems.

Why choose utility interconnected photovoltaic inverters?

In the construction of solar energy systems, the choice of inverter has a decisive influence on the overall performance of the system. What are the benefits of utility grid interconnected inverters?

A. Help users achieve power independence and reduce dependence on unstable power grids;

B. Through the grid access and energy storage scheduling, users can effectively reduce long term electricity costs and improve system economy. At the same time, in many countries that implement the net metering system (Net Metering), this type of inverter can also directly obtain policy subsidies to further improve the project return rate.

C. For engineering projects, utility interconnected photovoltaic inverters are also significantly superior to traditional single off grid or grid connected solutions in terms of system configuration flexibility, compatibility and intelligent management.

How to choose utility interconnected photovoltaic inverters?

Choosing utility interconnected photovoltaic inverters requires comprehensive consideration from multiple dimensions. Is the system used in areas with stable urban power grids or in remote areas with greater power outages? If the power grid fluctuates frequently or there are sudden outages, the inverter must have the ability to quickly and seamlessly switch to off grid working mode, and be used with a battery energy storage system to ensure that critical loads can continue to be powered when the mains power is interrupted. The energy storage system can also provide backup power at night or in rainy weather when solar radiation is insufficient, achieving energy autonomy.

In areas with stable power grids, such as Turkey, Poland, and Mexico, driven by national energy policies and the needs of residents and enterprises to save electricity bills, it is suitable to use on&off grid utility interconnected photovoltaic inverter. The inverter can be stably connected to the grid, when solar power generation is insufficient or there is no solar energy at night, the inverter can automatically obtain power from the grid to ensure that the load continues to operate without worrying about the risk of power outages. when the grid fluctuates slightly or users have off grid power supply needs, it can flexibly switch to off grid mode, and can respond to emergencies without the need for additional complex equipment. During the day, solar power is used for power supply first, and the excess power is stored in the battery, which is released at night or during peak hours, so as to achieve peak load shifting, increase the proportion of self generation and self use, and maximize economic benefits.

In order to better monitor the voltage and frequency of the power grid and adjust the output of the inverter accordingly. The voltage and frequency of the AC output of the inverter need to be controlled at a level compatible with the public power grid. At the same time, it has perfect protection functions, such as overvoltage protection, undervoltage protection, overcurrent protection, short circuit protection, etc. When the power grid is abnormal or the system fails, the circuit is quickly cut off to ensure the safety of equipment and personnel and extend the service life of the system.
